·??????? Group By: Aggregates data based on specific columns.

·??????? Join: Combines multiple tables based on a common column.

·??????? Split Column: Splits a column into multiple columns based on a ?????delimiter or position.

·??????? Pivot: Transforms data from rows to columns.

??

2. Data Modeling Functions:

·??????? Calculated Column: Create calculated columns in tables using DAX (Data Analysis Expressions) formulas.

·??????? Measure: Define measures using DAX to perform calculations on aggregated data.

·??????? Calculated Table: Create calculated tables based on DAX expressions.

·??????? Time Intelligence: Includes functions like TOTALYTD, SAMEPERIODLASTYEAR, and more for time-based analysis.

?

3. Data Visualization Functions:

·??????? Charts: Power BI provides a variety of chart types, including bar charts, pie charts, scatter plots, and more.

·??????? Tables and Matrices: Create tables and matrices to display data in a tabular format.

·??????? Maps: Display data on interactive maps using geographic fields.

·??????? KPIs: Create Key Performance Indicators to visualize important metrics.

·??????? Custom Visuals: You can import custom visuals or develop your own using the Power BI developer tools.

?

4. Calculated Columns and Measures:

·??????? ???- DAX Functions: Data Analysis Expressions (DAX) allows you to create calculated columns, measures, and calculated tables. It includes functions for aggregation, time intelligence, filtering, and more.

?

5. Data Connectors and Query Functions:

·??????? Power BI offers a wide range of data connectors to connect to various data sources, such as databases, cloud services, Excel files, and more.

·??????? Query functions in the Power Query Editor allow you to transform and shape data during the ETL (Extract, Transform, Load) process.

?

6. Customization and Personalization:

·??????? Themes: Customize the look and feel of your reports using themes and templates.

·??????? Custom Visuals: Create or import custom visualizations to extend Power BI's capabilities.

?

7. Power BI Service and Sharing:

·??????? Publish to Web: Share reports publicly using a web link.

·??????? Power BI Service: Collaborate with colleagues and clients by publishing reports to the Power BI service.

·??????? Power BI Embedded: Embed Power BI reports and dashboards into custom applications and websites.

?

8. Custom Functions and Extensions:

·??????? You can write custom functions in Power Query using the M language, allowing you to create reusable data transformation logic.

·??????? Power BI also supports the use of custom extensions and scripts to enhance functionality.

?

9. Advanced Features:

·??????? Drillthrough: Allows users to navigate from summary data to detailed data.

·??????? Bookmarking: Create bookmarks to save the current state of a report.

·??????? Parameterization: Allows users to input parameters to change the behaviour of a report or dashboard dynamically.

?

10. Data Security and Compliance:

·??????? Power BI offers features for data governance and compliance, including row-level security and encryption.

?

Power BI is highly extensible and customizable, with a vibrant community that contributes custom visuals and additional functionality. The use of DAX (Data Analysis Expressions) is fundamental in creating calculated columns, measures, and more advanced data modeling functions.

?

Power BI offers both a free desktop version and a paid cloud service (Power BI Service) that enables sharing and collaboration on reports and dashboards. It is widely used for data analysis and reporting in various industries to make data-driven decisions.
